A method and an apparatus for providing call routing in a network are disclosed. For example, the method receives a signaling message for a call, and determines if the signaling message contains information for determining if routing of the call requires an ENUM (tElephone Numbering Mapping) query. The method then processes the call by bypassing the ENUM query if the signaling message contains the information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for processing a call in a network, comprising: receiving, by a processor of a serving-call session control function, a signaling message for the call; determining, by the processor, the signaling message contains information for determining whether routing of the call requires a telephone numbering mapping query, wherein the information comprises a carrier identification code, wherein the carrier identification code identifies a carrier to which the signaling message is to be forwarded, wherein the network comprises an internet protocol network; and processing, by the processor, the call by bypassing the telephone numbering mapping query.
2. The method of claim 1 , wherein the information further comprises a predetermined prefix for bypassing a telephone numbering mapping processing.
3. The method of claim 2 , wherein the predetermined prefix is determined by a service provider.
4. The method of claim 1 , wherein the signaling message comprises a session initiation protocol signaling message.
5. The method of claim 1 , wherein the internet protocol network comprises an internet protocol multimedia subsystem network.
6. The method of claim 5 , wherein the internet protocol multimedia subsystem network comprises a voice over internet protocol network.
7. The method of claim 1 , further comprising: forwarding the signaling message to the carrier as identified by the carrier identification code.
8. A non-transitory computer-readable medium storing a plurality of instructions which, when executed by a processor of a serving-call session control function, cause the processor to perform operations for processing a call in a network, the operations comprising: receiving a signaling message for the call; determining the signaling message contains information for determining whether routing of the call requires a telephone numbering mapping query, wherein the information comprises a carrier identification code, wherein the carrier identification code identifies a carrier to which the signaling message is to be forwarded, wherein the network comprises an internet protocol network; and processing the call by bypassing the telephone numbering mapping query.
9. The non-transitory computer-readable medium of claim 8 , wherein the information further comprises a predetermined prefix for bypassing a telephone numbering mapping processing.
10. The non-transitory computer-readable medium of claim 9 , wherein the predetermined prefix is determined by a service provider.
11. The non-transitory computer-readable medium of claim 8 , wherein the signaling message comprises a session initiation protocol signaling message.
12. The non-transitory computer-readable medium of claim 8 , wherein the internet protocol network comprises an internet protocol multimedia subsystem network.
13. The non-transitory computer-readable medium of claim 12 , wherein the internet protocol multimedia subsystem network comprises a voice over internet protocol network.
14. The non-transitory computer-readable medium of claim 8 , further comprising: forwarding the signaling message to the carrier as identified by the carrier identification code.
15. An apparatus for processing a call in a network comprising: a processor of a serving-call session control function; and a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising: receiving a signaling message for the call; determining the signaling message contains information for determining whether routing of the call requires a telephone numbering mapping query, wherein the information comprises a carrier identification code, wherein the carrier identification code identifies a carrier to which the signaling message is to be forwarded, wherein the network comprises an internet protocol network; and processing the call by bypassing the telephone numbering mapping query.
16. The apparatus of claim 15 , wherein the information further comprises a predetermined prefix for bypassing a telephone numbering mapping processing.
17. The apparatus of claim 16 , wherein the predetermined prefix is determined by a service provider.
18. The apparatus of claim 15 , wherein the signaling message comprises a session initiation protocol signaling message.
19. The apparatus of claim 15 , wherein the internet protocol network comprises an internet protocol multimedia subsystem network.
20. The apparatus of claim 15 , further comprising: forwarding the signaling message to the carrier as identified by the carrier identification code.
